What's the difference between glycosine and glyoxal?
Glycosine
Definition:
(n.) An organic base, C6H6N4, produced artificially as a white, crystalline powder, by the action of ammonia on glyoxal.
Example Sentences:
Glyoxal
Definition:
(n.) A white, amorphous, deliquescent powder, (CO.H)2, obtained by the partial oxidation of glycol. It is a double aldehyde, between glycol and oxalic acid.
Example Sentences:
(1) Therefore, all the results suggest that 1O2 formed from glyoxal is related to its mutagenesis, but that neither O2- nor H2O2 is intracellularly predominantly related to it.
(2) In addition, the possible mutagenic effect of glyoxal was assessed in postmeiotic cells up to 7 days after treatment.
(3) The complement-fixing activity of the virus was not reduced by methyl glyoxal treatment.
(4) The distribution of hydroxyproline oxidase, hydroxyoxoglutarate aldolase and alanine-glyoxalate transaminase were determined in detail.
(5) The location of calcium in a rapid-frozen and freeze-substituted maturation stage enamel organ of the rat incisors was demonstrated by means of the glyoxal bis(2-hydroxyanil) (GBHA) staining method, which formed insoluble red precipitates of calcium-GBHA complex.
(6) Based on the assumption that an inactivating particle keeps the channel closed, several protein-modifying agents including trypsin, papain, glyoxal, and phenylglycoxal that remove Na+-channel inactivation were tested.
(7) The extent of glyoxal reaction can be easily and sensitively measured using an assay based on the intercalation of ethidium into duplex DNA.
(8) The strains did not grow on oxalate, glyoxalate, glycolate, malonate or propionate.
(9) Condensation of the glyoxal obtained by cupric acetate oxidation of 21-hydroxycorticosteroids with acetous phenylhydrazine reagent affords a near UV chromophore.
(10) Three of the base replacements led to a more compact secondary structure of RNA segment 8, which seems to be responsible for the faster migration rate during PAGE and which seems to resist, at least partially, the treatment with glyoxal.
(11) By using a histofluorescent stain (glyoxalic acid) and a histochemical stain (thiocholine) in 17 fresh cadavres, we have demonstrated that the sympathetic fibres arise from sacral sympathetic ganglia.
(12) The chemicals studied were: bleomycin, t-butyl hydroperoxide, chromium trioxide, cumene hydroperoxide, formaldehyde, glyoxal, glutaraldehyde, hydrogen peroxide, paraquat, and phenylhydrazine.
(13) It was proved to be 8-(1'-D-ribityl)lumazine, which appeared to have been formed by a reaction between glyoxal and a possible intermediate in the cells.
(14) In this paper, both glyoxal bis(4-phenyl-3-thiosemicarbazone) (GBPT) and bathocuproine disulphonate (BCDS) methods for copper have been applied to the spectrophotometric determination of copper in foods, feedingstuffs and plants.
(15) MGR I was specific to 2-oxoaldehydes [glyoxal, methylglyoxal (Km = 15.4 mM) and phenylglyoxal], whereas MGR II was active on both 2-oxoaldehydes [glyoxal (Km = 10 mM), methylglyoxal (Km = 1.43 mM), phenylglyoxal (Km = 4.35 mM) and 4,5-dioxovalerate] and some aldehydes (propionaldehyde and acetaldehyde).
(16) The glyoxal bis(guanylhydrazone) chain of the EMGBG cation deviated strongly from planarity, thus differing dramatically from the corresponding chains of the glyoxal, methylglyoxal and propylglyoxal analogs.
(17) In contrast to unmodified tRNA, glyoxalated tRNA was rapidly degraded upon injection.
(18) Glyoxal treatment significantly increased the incidence of adenocarcinomas in the pylorus of the glandular stomach of rats pretreated with MNNG and sodium chloride.
(19) Total cytoplasmic or nuclear polyadenylated RNAs from infected cells were denatured with glyoxal, separated by electrophoresis on agarose gels, and transferred to diazobenzyloxymethyl paper.
(20) With a single oral high-dose treatment of glyoxal, a great decline in the incorporation of L-[3H]leucine was shown particularly in the liver, and this probably led in part to a reduction in the serum protein levels in rats following subchronic exposure to glyoxal.
